|
|
http://folding.typepad.com/news/2012/07/bonus-for-a4-core-based-project.html
The reason for the bounty, is that many of the A4 projects are considered to be 'vanguard' - giving earlier predictive or probabilistic data to guide F@H on where to focus the bulk of the detailed, heavy-lifting WUs.
But this, just after CrunchyFrog lost his awesome CPU/SMP shrubbers?
Rotten luck/timing!
BTW: I opted to set my FX-8120 to use all 8 cores (instead of 6).
I suspect that each of these A4 WUs will take many hours/days to complete, even with SMP.
But they ought to produce some meatier points!
Hmmm...why am I thinking "BACON!"?????? _________________ Click here for...KWSN F@H team summary at EOC

Do A4 core WUs still require at least a 4 core CPU with HT? _________________

10% hardly qualifies as a bounty.
You'd think these points came directly out of the project admin's pocket. ![Rolling Eyes](images/smiles/icon_rolleyes.gif) _________________

------------------------------
FAHcore_A4.exe is launched for SMP (symmetric multicore processing) processors.
HT (hyper-threading) is a feature unique to Intel processors [for now] which functionally doubles the number of CPU cores that the O/S sees.
I think even a dual-core AMD or Intel (even without HT) processor would qualify.
The 'A4' name is just a hexadecimal version-suffix for the current SMP-optimized code executor.
------------------------------
The latest stable GPU core is '15'; but the '16' version (still in beta testing) is an attempt to unify the ATI and NV cores using OpenCL (CL = Computational Library).
Nvidia has had to make some concessions and do some extra work to implement this because the CUDA framework was not always compatible (or easily interface-able) with OpenCL.
ATI apparently had less difficulty, since they had already loosely followed OpenCL design concepts in their CCC framework for quite some time.
